摘要
本文利用~1H、^(13)C-NMR测定岩样抽提物及芳烃馏分,结合元素分析数据对有机质的演化、类型及沉积环境等进行了研究,探讨了用NMR判别生油门限深度、评价生油母质、确定石油烃类主要生油层段和研究生油机理等,提出芳烃馏分的∑芳氢(δ≥6.7ppm)/∑链氢、三类氢(H_β+H_Υ)百分含量是成熟度的新参数。
Soluble extracts of source rock and aromatic fraction have been analyzed by H and C-NMR. Combining with elemental analysis, the study on evolution, type and sedimental environment of the organic matter is presented. And the paper has also probed the use of NMR in distinguishing threshold depth,source rock and principal stage of oil formation and studing mechanism of oil formation.lt is sug-gested that 2 aromatic hydrogen (б≥6.7ppm)/∑ aliphatic saturated hydrogen, the third hydiogen(Hβ+Hγ) % of aromatic fraction are new parameters of maturity.
